Despite all of the publicity surrounding the Ray Rice case and outrage that forced NFL commissioner Roger Goodell to overhaul the league's domestic violence policy, another football player allegedly has assaulted a woman.

San Francisco 49ers defensive end Ray McDonald was arrested Sunday morning and charged with felony domestic violence, San Jose police said. McDonald posted $25,000 bail and was released from jail about six hours after he was booked, according to a report by NBC Bay Area.

The Sacramento Bee reported that McDonald, who was celebrating his birthday, was involved in an argument with his fiancee, who had bruises on her arms and neck. She is pregnant, the report said. The report said teammates Vernon Davis and Demarcus Dobbs were present.

McDonald, 29, was arrested just before 3 a.m. at a San Jose residence , police said via the department's official Twitter account. He was released about six hours later. McDonald has a court date of Sept. 15, the day after the Niners play a home game on Sunday night game against the Chicago Bears.

"The 49ers organization is aware of the recent reports regarding Ray McDonald and we take such matters seriously," the 49ers said in a statement Sunday morning. "As we continue to gather the facts, we will reserve further comment."

Coach Jim Harbaugh has warned 49ers players that domestic violence would not be tolerated.

“He said that we can do anything in the world and we can come and talk to him and he’ll forgive us -- except put our hands on women,” former 49ers safety Donte Whitner said in 2012. “If you put your hands on a woman, then you’re done in his book.”

Under the NFL's new policy -- enacted when Goodell admitted he screwed up by suspending Rice for only two games -- a first offense would result in a six-game suspension. A second domestic violence violation would lead to an indefinite ban of at least a year.
